Depositsof oil shale occur around the … half shark, half whale. [31] Hydrodesulfurization and hydrodenitrogenation can address these problems and result in a product comparable to benchmark crude oil. "About technical terms of oil shale and shale oil", "Oil & Gas Shales, Definitions & Distribution In Time & Space. The shale revolution, which kicked off in 2006 with natural gas and later shifted to crude oil in 2010, propelled the United States into the world’s top producer and a net exporter of oil and gas, weaning the country from its dependence on foreign oil. Thermal dissolution involves the application of solvents at elevated temperatures and pressures, increasing oil output by cracking the dissolved organic matter. Shale oil is an unconventional oil produced from oil shale rock fragments by pyrolysis, hydrogenation, or thermal dissolution. Shale has huge competition to fill remaining oil demand. "[23][24], The amount of oil that can be recovered during retorting varies with the oil shale and the technology used. Shale oil is an unconventional oil that is extracted from shale rock. Info. After over 50 cases brought before, and thrown out of, US courts, including the Supreme Court, hundreds of Trump supporters, claiming to be a million supporters, continued to cry and protest and chant outside the White House, like a bunch of voteflakes. A report by EASAC to the Committee on Industry, Research and Energy of the European Parliament", American Association of Petroleum Geologists, "Geology and resources of some world oil-shale deposits. Kerogen is the source of virtually all crude oil. Oil Shale. Shale oil is the oil that is produced in an informal way from the oil shale rock formations by using different techniques. Shale oil is made possible thanks to advances in horizontal drilling and fracking. Another 20% will teeter on the edge. [28], The properties of raw shale oil vary depending on the composition of the parent oil shale and the extraction technology used. 2,286,000 bpd. shale meaning: 1. a type of soft, grey rock, usually formed from clay that has become hard, that breaks easily…. Mostly Texas, though some production comes from New Mexico. Different methods produce shale oil with different properties. Meaning of shale oil. Many people get confused by the terms Oil Shale and Shale Oil; however, both are completely different. It is generally less economical than conventional crude oil. Shale oil and shale gas formations can be found around the world. Shale oil extraction has been made viable thanks to the development of horizontal drilling techniques and hydraulic fracturing (fracking), which allows oil and natural gas producers to efficiently extract resources from shale rock and other low-permeability rock formations. It has been described that raw shale oil has a mild carcinogenic potential which is comparable to some intermediate refinery products, while upgraded shale oil has lower carcinogenic potential as most of the polycyclic aromatics are believed to broken down by hydrogenation. The “Shale Revolution” refers to the combination of hydraulic fracturing and horizontal drilling that enabled the United States to significantly increase its production of oil and natural gas, particularly from tight oil formations, which now account for 36% of total U.S. crude oil production. Distillate oils from the Kiviter process can also be used as diluents for petroleum-originated heavy oils and as an adhesive-enhancing additive in bituminous materials such as asphalt. The emergence of U.S. shale production seems to be playing a large role in anchoring long-term oil prices. Learn more. Fushun Mining Group reports producing 300,000 tons per year of shale oil from 6.6 million tons of shale, a yield of 4.5% by weight. Hydrocarbons are substances made entirely of hydrogen and carbon. [26] VKG Oil claims to produce 250,000 tons of oil per year from 2 million tons of shale, a yield of 13%. Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. [2][3], Oil shale was one of the first sources of mineral oil used by humans. Definition of oil shale, with etymology, pronunciation (phonetic and audio), synonyms, antonyms, derived terms and more about the word oil shale. In the aftermath of the 2014 oil crash, U.S. shale learned a painful lesson: Not all hedging strategies pay off. These processes convert the organic matter within the rock (kerogen) into synthetic oil and gas. Afterwards, it was used as a raw material for chemical intermediates, pure chemicals and industrial resins, and as a railroad wood preservative. The refined products can be used for the same purposes as those derived from crude oil. For crude oil occurring in shale reservoirs, see. The term "shale oil" is also used for crude oil produced from shales of other very low permeability formations. Video shows what oil shale means. Hydrocarbon s are substances made entirely of hydrogen and carbon. Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced, called shale oil (not to be confused with tight oil—crude oil occurring naturally in shales). ‘Carbonaceous shale, including oil shale, occurs in beds of clayey to silty mudrock from 0.3 to 3 m thick.’ ‘The term ‘fossil fuels’ is commonly used for the materials tar sands, oil, gas condensates, natural gas, coal, and oil shale and their products.’ sedimentary rock - rock formed from consolidated clay sediments. [11] The oil was used as fuel, as a lubricant and lamp oil; the Industrial Revolution had created additional demand for lighting. The global economic expansion of the last decade was in large part sustained by the increase in shale oil production, without which oil price spikes would have destroyed the recovery. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. The refined products can be used for the same purposes as those derived from crude oil. [27] Petrobras produces in their Petrosix plant 550 tons of oil per day from 6,200 tons of shale, a yield of 9%. The definition of Shale Oil is followed by practically usable example sentences which allow you to construct your own sentences based on it. Shale … A typical shale oil composition includes 0.5–1% of oxygen, 1.5–2% of nitrogen and 0.15–1% of sulfur, and some deposits contain more heteroatoms. The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas. Developing Onshore Shale Gas and Oil – Facts about ‘Fracking’ 3 Developing Onshore Shale Gas and Oil – Facts about ‘Fracking’ Shale gas and oil could provide the UK with greater energy security, growth, jobs and tax revenue. The main difference between crude oil and shale oil is the process of generation of each type of oil. Although shale-oil plays with oil stored in open-fractured shale have been pursued for more than 100 yr, organic-rich and low-permeability shales and hybrid shale-oil systems are now being pursued based on knowledge and technologies gained from production of shale-gas resource systems and likely hold the largest untapped oil resource potential. [15], Shale oil is extracted by pyrolysis, hydrogenation, or thermal dissolution of oil shale. shale-oil: A trade-name of mineral oil produced by the destructive distillation of bituminous shale, chiefly in the south of Scotland. Definition - What does Oil Shale mean? The offers that appear in this table are from partnerships from which Investopedia receives compensation. Shale oil, in fossil fuel production, either a synthetic crude oil that is extracted from oil shale by means of pyrolysis or a naturally occurring crude oil that is extracted from underground shale deposits by means of fracking (hydraulic fracturing).. Shale oil refers to hydrocarbons that are trapped in formations of shale rock. Permeability refers to the ability of fluids and gases to pass through the rock. ‘Carbonaceous shale, including oil shale, occurs in beds of clayey to silty mudrock from 0.3 to 3 m thick.’ ‘The term ‘fossil fuels’ is commonly used for the materials tar sands, oil, gas condensates, natural gas, coal, and oil shale and their products.’ The page not only provides Urdu meaning of Shale Oil but also gives extensive definition in English language. Oil shale shouldn't be confused with "shale oil," also called “tight oil,” a more commonly produced type of unconventional oil that's found trapped in limestone or sandstone rocks. Definition of oil shale. Liquid and gaseous hydrocarbons can be extracted from oil shale, but the rock must be heated and/or treated with solvents. The techniques, such as thermal dissolution, pyrolysis and hydrogenation lead to the conversion of the organic matter into artificially matured oil. Shale oil definition: an oil distilled from shales and used as fuel | Meaning, pronunciation, translations and examples [1] The International Energy Agency recommends to use the term "light tight oil" and World Energy Resources 2013 report by the World Energy Council uses the term "tight oil" for crude oil in oil-bearing shales. : a crude dark oil obtained from oil shale by heating. The shale industry will be the greatest short and medium-term contributor to the supply destruction that the current oil price environment is inflicting on the global oil industry. The U.S. Energy Information Administration (EIA) estimates that more than 300 billion barrels of shale oil might be technically recoverable, making up approximately 10% of total crude oil resources. (noun) [44][45] Worldwide production of shale oil was estimated at 17,700 barrels per day (2,810 m3/d) in 2008. Because oil shale requires mining and energy-intensive refining processes, it's a substantially dirtier energy source than conventional liquid oil. a sedimentary rock containing kerogen from which petroleum-like shale oil can be produced by pyrolysis, hydrogenation, or thermal dissolution.. oil shale … Petroleum and natural gas are probably the most familiar hydrocarbons. Proper usage and audio pronunciation (plus IPA phonetic transcription) of the word oil shale. Shale oil is also different than oil shale, which is a type of sedimentary rock that has low permeability and bituminous-like (consisting mainly of hydrocarbons) solids that can be liquefied during the extraction process. It is used in heating oil, marine fuels, and the production of various chemicals. Oil shale - Oil shale - Organic content: The organic matter contained in oil shale is principally kerogen, a solid product of bacterially altered plant and animal remains that is not soluble in traditional petroleum solvents. 1,144,000 bpd Shale Oil Production. The resulting oil can be used immediately as a fuel or upgraded to meet refinery feedstock specifications by adding hydrogen and removing impurities such as sulfur and nitrogen. oil shale - shale from which oil can be obtained by heating. [40] Upgrading shale oil into transport fuels requires adjusting hydrogen–carbon ratios by adding hydrogen (hydrocracking) or removing carbon (coking). George P. Mitchell pioneered modern shale drilling, which combined the decades-old technologies of hydraulic fracturing, or fracking, and horizontal drilling to crack open shale rock and tap into previously inaccessible reservoirs of crude and natural gas. This website contains assessments and geologic reports , as well as spatial and tabular datasets, fischer assays and well logs from USGS oil shale research studies. “Shale wells lose as much as 70 percent of their production in the first year, meaning that explorers have to constantly pour money into more drilling just to maintain production. Final report on US Department of Energy", "A study on the EU oil shale industry viewed in the light of the Estonian experience. Shale oil is a substitute for conventional crude oil; however, extracting shale oil from oil shale is more costly than the production of conventional crude oil both financially and in terms of its environmental impact. In The History of On-Shore Hydrocarbon Use in the UK", "Studies of the Scottish oil shale industry. Information about shale oil in the AudioEnglish.org dictionary, synonyms and antonyms. [14], The production of shale oil has been hindered because of technical difficulties and costs. Definition of oil shale in the AudioEnglish.org Dictionary. humic shale - shale that is rich in humic acids. A fissile rock composed of layers of claylike, fine-grained sediments. Liquid and gaseous hydrocarbons can be extracted from oil shale, but the rock must be heated and/or treated with solvents. This temperature and pressure vary with the depth of the reservoir. Primary uses include heating oil, marine fuel, and the production of various chemicals. [17][18][19][20], A critical measure of the viability of extraction of shale oil lies in the ratio of the energy produced by the oil shale to the energy used in its mining and processing, a ratio known as "Energy Returned on Energy Invested" (EROEI). The oil and natural gas industry often refers to tight oil rather than shale oil when estimating production and resources. Shale oil outpaced OPEC in terms of production increase in the past decade—between 2008 and 2018, OPEC added 2.05 mb/d or 17.6 percent of the global supply increase, while the United States supplied 8.53 mb/d of new oil, accounting for 73.2 percent of the increase. HOUSTON/NEW YORK (Reuters) - U.S. oil and gas shares and drilling activity are edging higher, but a disastrous year for the energy industry means the go-go days of the shale … The oil resulting from this processing can either be used immediately as a fuel or processed some more to meet r… Tight oil has become the largest source of domestic oil in the United States. [11][14][15] In response to rising petroleum costs at the turn of the 21st century, extraction operations have commenced, been explored, or been renewed in the United States, China, Australia and Jordan. Decomposition takes place most quickly at a temperature between 480 and 520 °C (900 and 970 °F). [22] Royal Dutch Shell reported an EROEI of three to four in 2006 on its in situ development in the "Mahogany Research Project. In addition, the process is sometimes criticized for the destructive impact on the environment. Hydraulic fracturing stimulates better flow in oil and gas plays by injecting a high-pressure liquid and sand mixture into the wellbore. 54–56. The differing properties of the raw oils call for correspondingly various pre-treatments before it can be sent to a conventional oil refinery. Shale oil can also contain significant quantities of heteroatoms. Shale oil usually contains large quantities of olefinic and aromatic hydrocarbons. The kerogen deposits on shale oil rocks gently convert into crude oil by natural processes. [30][31] Generally, the oil is less fluid than crude oil, becoming pourable at temperatures between 24 and 27 °C (75 and 81 °F), while conventional crude oil is pourable at temperatures between −60 to 30 °C (−76 to 86 °F); this property affects shale oil's ability to be transported in existing pipelines. Oil shale definition, a black or dark-brown shale or siltstone rich in bitumens, from which shale oil is obtained by destructive distillation. Countries with the largest amount of technically recoverable shale oil resources include Russia, the United States, China, Argentina, and Libya. See more. [6] In 1596, the personal physician of Frederick I, Duke of Württemberg wrote of its healing properties. Shale oil comprises more than a third of the onshore production of crude oil in the lower 48 states. That is, oil shale is the sedimentary rock formation containing a type of organic matter called kerogen that yields oil and gas. Crude oil occurs in underground at elevated pressure and temperature. Production from tight oil plays reached 6.5 million barrels per day and totaled nearly 60% of total U.S. oil production in 2018. The Marcellus Shale lies under the Appalachian Basin, and spreads across New York, Pennsylvania, Ohio, West Virginia, Maryland, Tennessee, Virginia and Kentucky. Oil shale is a type of sedimentary rock formation that is used to produce oil and gas. Shale drilling r… Shale oil is a type of unconventional oil found in shale formations that must be hydraulically fractured to extract the oil. [7] Shale oil was used to light the streets of Modena, Italy at the turn of the 18th century. Scientific Investigations Report 2005–5294", "Using neoteric solvents in oil shale studies", "Energy and the U.S. Economy: A Biophysical Perspective", "Oil Shale Test Project. Up to 1/3 of the rock can be solid kerogen. Eagle Ford Shale. Since 2014, U.S. shale oil has created a boom in domestic crude oil production. [16][17] The pyrolysis of the rock is performed in a retort, situated either above ground or within the rock formation itself. The oxygen within the oil, present at higher levels than in crude oil, lends itself to the formation of destructive free radicals. The Marcellus Shale lies under the Appalachian Basin, and spreads across New York, Pennsylvania, Ohio, West Virginia, Maryland, Tennessee, Virginia and Kentucky. [39][40], Shale oil produced by some technologies, such as the Kiviter process, can be used without further upgrading as an oil constituent and as a source of phenolic compounds. [31][43], Global technically recoverable oil shale reserves have recently been estimated at about 2.8 to 3.3 trillion barrels (450×10^9 to 520×10^9 m3) of shale oil, with the largest reserves in the United States, which is thought to have 1.5–2.6 trillion barrels (240×10^9–410×10^9 m3). Oil shale definition: a fine-grained shale containing oil , which can be extracted by heating | Meaning, pronunciation, translations and examples [7] The British Crown granted a patent in 1694 to three persons who had "found a way to extract and make great quantities of pitch, tarr and oyle out of a sort of stone. A 1984 study estimated the EROEI of the various known oil-shale deposits as varying between 0.7–13.3. [21] More recent studies estimates the EROEI of oil shales to be 1–2:1 or 2–16:1 – depending on whether self-energy is counted as a cost or internal energy is excluded and only purchased energy is counted as input. Meaning of oil shale. What does shale mean? [15] About one sixth of the oil shales in the Green River Formation have a relatively high yield of 25 to 100 US gallons (95 to 379 l; 21 to 83 imp gal) of shale oil per ton of oil shale; about one third yield from 10 to 25 US gallons (38 to 95 l; 8.3 to 20.8 imp gal) per ton. Definition of shale oil in the AudioEnglish.org Dictionary. shale gas definition: 1. natural gas that is found in shale (= a type of soft, grey rock): 2. natural gas that is found…. [7][12][13], During the late 19th century, shale-oil extraction plants were built in Australia, Brazil and the United States. Mineral particles and metals are often present as well. The Government is encouraging safe and environmentally sound exploration to determine our shale potential. The remaining shale oil companies are hoarding cash to stay alive. You can also find multiple synonyms or similar words of Shale Oil. shale - a sedimentary rock formed by the deposition of successive layers of clay. Up to 1/3 of the rock can be solid kerogen. Shale's struggles are making news around the globe and could have various implications for the Canadian oil and gas sector, whether it's on prices or discussions on energy security. Nevertheless, U.S. production of shale oil has increased significantly since 2010, driven by technological improvements that have reduced drilling costs and improved drilling efficiency in major shale producing areas, such as the Bakken, Eagle Ford, and the Permian Basin. Shale oil has not to exposed to sufficient pressure and temperature to convert trapped hydrocarbons into crude oil. As of 2008, most oil shale industries perform the shale oil extraction process after the rock is mined, crushed and transported to a retorting facility, although several experimental technologies perform the process in place (in-situ). An EROEI of 2 (or 2:1 ratio) would mean that to produce 2 barrels of actual oil the equivalent in energy of 1 barrel of oil has to be burnt/consumed. Natural gas liquids are components of natural gas that are separated from the gas state in the form of liquids. Learn more. First, let us understand more about shale rock. Kraushaar, Jack P., and Robert A. Ristinen. The rise of U.S. shale shook up world energy markets in recent years. Unconventional oil is crude oil that has been identified or extracted using novel methods. This is because tight oil may be extracted from rock formations that, in addition to shale formations, include sandstone and carbonates. Tight oil differs from shale oil because tight oil can be extracted from not just shale formations but also sandstone and carbonates. U.S. oil and gas shares and drilling activity are edging higher, but a disastrous year for the energy industry means the go-go days of the shale boom may be gone for good. Oil shale is a rock that contains significant amounts of organic material in the form of kerogen. Definition of shale oil. Oil shale is a rock that contains significant amounts of organic material in the form of kerogen.

Crude oil production in the U.S. shale patch is set to decline by 68,000 bpd next month, with every play registering declines in output except the Permian Now, COVID-19 has put the sector under pressure. "[7][8][9] Later sold as Betton's British Oil, the distilled product was said to have been "tried by diverse persons in Aches and Pains with much benefit. The temperature at which the kerogen decomposes into usable hydrocarbons varies with the time-scale of the process; in the above-ground retorting process decomposition begins at 300 °C (570 °F), but proceeds more rapidly and completely at higher temperatures. It consists mainly of hydrocarbons of the paraffin, olefine, and crotonylen series, and yields as the principal commercial products illuminating- … Fracturing shallow, hard rock wells to extract oil dates back to the 1860s. States. Essentially, it is oil trapped in solid form inside various rock formations. Producing shale oil from shale rock has been traditionally more expensive than conventional crude oil. (Ten US gal/ton is approximately 3.4 tons of oil per 100 tons of shale.) Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Vol.1 History of the industry, working conditions and mineralogy of Scottish and Green River formation shales. What does shale oil mean? Oil shale, despite the name, does not actually contain oil, but is a precursor of oil that is converted to crude oil when heated. [37][38] Olefins form insoluble sediments and cause instability. The oil price that companies need to profitably drill new wells has closely tracked prices for long-dated oil futures in recent years.
